	// Auth may contain an [Actor] that performs a transaction
	//
	// We provide the [txID] here because different actions like to use this as
	// a unique identifier for things created in an action.

	// Key distinction with "Auth" is the payment of fees. All non-fee payments
	// occur in Execute but Auth handles fees.

	// The weird part of this is that they both need a shared understanding of
	// balance tracking. Is it weird Auth then needs an understanding of storage
	// structure? Not sure there is an easier way.

	// auth (like where to pull balance from on a transfer).
